While battling Doombala, the Mighty Crusaders accidentally awaken Eterno the Tyrant who had escaped the destruction of Atlantis by going into suspended animation. Eterno tries to turn the Mighty Crusaders evil, but is defeated by a lowly Atlantean mosquito.

Indexer Notes

3-part story.

Adhesive-Man, The Living Coil, King Ogre, and The Purple Menace are listed twice in the character section. They first appear as comic book enthusiasts dressed as these characters at a convention and then Eterno uses his powers to summon the real villains themselves.
